To all whom it may concern:

Be it known that we, JOHN KLEINBERGER and RUDOLPH STERN, respectively acitizen of the United States and a subject of the Emperor ofAustria-Hungary, and respectively residing at Brooklyn, in the county ofKings and State of New York, and New York city, in the county and Stateof New York, have invented certain new and useful Improvements inTick-Adjusting Mechanism for Lamps and Lanterns; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in lamps, lanterns, and the like,and particularly to means for adjusting the wick thereof, and has for anobject the arrangement of adjusting means that may be operated from theexterior of the lamp.

Another object in view is the provision of a lantern or lamp with aremovable well, and means for adjusting the wick by the rotation of thethumb member located on the outside or bottom of the well.

A still. further object of the invention is the arrangement of areciprocating rack and guide for moving a wheel connected with the wickadjusting mechanism so that upon the' reciprocation of the rack the gearwill be rotated for varying the position of the wick, and a screw foradjusting the rack that extends to the exterior of the lamp formanipulation whereby upon the rotation of the. screw the wick will beraised and lowered according to the direction of movement of the screw.

With these and other objects inview the invention comprises certainnovel constructions, combinations and arrangement of parts as will behereinafter more fully described and clamed.

In the accompanying drawings: Figurel is a side elevation of a lantern,certain parts being broken away in order to better disclose theinvention. Fig. 2 is a fragmentary plan view of the well of the lanternshowing the wick adjusting mechanism connected therewith. Fig. 3 is anenlarged fragmentary side elevation of the well with the wick adjustingmechanism yconnected therewith. Fig. t is an enlarged detail perspectiveview of the rack and guiding means. Fig. 5 is a side elevation of thewell or font removed with the reciprocating slide turned for permittingthe removal of the burner from the font. Fig. 6 is a side elevation ofthe font or well looking directly at the wick controlling gear, with thereciprocating member raised but not turned. Fig. 7 is a top plan view ofthe structure shown in Fig. 5, the reciprocating member being turned andalso the burner being shown turned in dotted lines.

In the construction of a lantern according to the present invention itis aimed among other things to provide an eficient lantern in which aproper adjustment of the wick may be made without removing the well orwithout opening the lantern. In accomplishing this purpose a gear wheelis rigidly secured to the rotating shaft upon which is mounted a wickfeeding or controlling mechanism. The gear wheel is arranged to meshwith a reciprocating rack that has secured thereto a guide for holdingthe rack in mesh with the gear wheel so that upon the reciprocation ofthe rack the gear wheel will be rotated, and consequently the wick willbe forcedl upward or downward according to the rotation thereof. Theguide for the rack is rigidly secured to the rack and is formed with athreaded projection through which extends a threaded adjusting member orscrew which is connected with the well and extends below the bottomthereof or to a position outside of the lantern when the well is inplace, and is permitted a free rotation but not any longitudinalmovement. By this arrangement whenever the screw is rotated the samewill force the lug on the guide upward or downward as the case may be,and consequently reciprocate the guide and the rack, whereby a'rotarymovement will be conveyed to the gear for regulating the position of thewick.

In order that the invention may be more fully understood an embodimentof the same is shown in the accompanying drawings, in which l indicatesthe body of a lamp that may be of any desired kind. Removably mounted inthe body l is a well 2. The well 2 is inserted and removed from thebottom and is held in place by spring catches 3 and t clamping orsnapping over a flange 5 formed on body l. 'Ihe well is provided with awick G that is controlled by any desired feeding mechanism (not shown)which in turn is controlled by a shaft 7. rlhe wick feeding mechanismmay be of any desired kind, and as the same forms no part of the presentinvention will not be further described. Rigidly secured to the shaft 7is a gear wheel 8 which is arranged to mesh with a rack 9 that isrigidly secured into a guiding member 10. rl`he guiding member 10 isformed with a turned over portion 11 that, together with the main bodyof the guiding member, forms a groove for holding the gear opposite thegear wheel 8. A slot 12 is formed in the guiding member which permitsthe guide 10 to reciprocate or slide over the shaft 7, and toconsequently hold the rack 9 in engagement with the gear wheel S. Bythis construction and arrangement the slot 12 acting on shaft 7 holdsthe rack against the wheel 8 and turned over portion 11 forms the guidefor holding the gear wheel and the rack in the same plane. Projectingoutward from the turned over portion 11 is a lug 13 that is providedwith an aperture passing therethrough that is threaded for receiving athreaded bolt or screw 14. rlhe threaded bolt 14 extends substantiallyparallel with the wick and at right angles to the shaft 7 and is adaptedupon rotation to reciprocate guide 10, and rack 9 carried thereby. Thebolt or screw 14 passes through a housing 15, and is prevented anylongitudinal movement by having secured thereto a stop 16 at the upperend of the housing 15, and a thumb member 17 at the lower end of thehousing 15. The threaded thumb member 17 is positioned on the exteriorof the entire lantern or below the well so as to be readily operatedwithout removing the well from the body 1 of the lantern. In order thatthe thumb member 17 may not project downward a sufficient distance tostrike any article upon which the lantern is placed the bottom of thewell 2 is offset at 18 for accommodating the thumb member.

After the wick has been lighted the catches 3 and 4 are grasped andforced inward until the well is permitted to enter the body 1 of thelantern and take the position shown in Fig. 1, or if desired the wellmay be bodily forced into the position shown in Fig. 1, the catches 3and 4 by their resilient nature permitting such action. The wick G thenmay be regulated to any desired height and turned up and down withoutremoving the well from the body 1 which is of great advantage in usewith marine lanterns and other lanterns or lamps used out in the openwhere the lamp is subject to the action of the wind. Upon the rotationof thumb member 17 screw 14 is moved and by being threaded intoprojection 13 will reciprocate or move upward or downward the projectionor extension 13. As extension 13 is rigidly secured to guide 10 and asguide 10 is rigidly secured to rack S) the rack will be moved up or downtogether with extension 13 as screw 14 is rotated in either direction.Upon the reciprocation of rack 9 gear wheel S will be rotated and alsoshaft 7, and con` sequently the feeding mechanism of wicl G will beoperated for regulating the position of wick 6.

It will be noted that the invention may be applied to any form of burnerby merely taking off the ordinary thumb piece on the burner andsubstituting therefor a gear wheel S and then applying the remainingparts of the adjusting mechanism.

In using the adjusting mechanism no disadvantage is experienced inremoving and then applying the burner to the well or font. In order toremove the burner all that is necessary is to turn the thumb piece ormember 17 until the reciprocating member 10 has been moved upward tosubstantially the position shown in Fig. G. The same is then turned tothe position shown in Figs. and 7. This will permit a free rotation ofthe burner until the same is entirely disconnected. The turning of thereciprocating rack carrying member 10 to the position shown in Figs. 5and 7 is very desirable as the same is entirely ont of the way of thegear wheel S as the same moves upward when unscrewing the burner. Afterthe well has been filled the burner may be replaced and then the slidingmember 10 brought to its correct position as seen in Fig. 1. This ideaof ready removability of the burner is an important feature of theinvention as by the particular construction and arrangement of thevarious parts the ready removability is accomplished withoutcomplicatedmechanism and delicate parts.
